A traverse (almost a square) has the following measured interior angles (in
counterclockwise order): A = 91 degrees 22 minutes; B = 88 degrees 31 minutes; C = 89
degrees 33 minutes; D = 90 degree 18 minutes. The bearing of course AB is S 46
degrees 18 minutes W. Sketch the traverse. Adjust the angles for closure and compute
the bearing of course CD
